Improved forearm rotation even after early conversion to below-elbow cast for non-reduced diaphyseal both-bones forearm fractures in children: a secondary 7.5-year follow up of a randomized trial.

ABSTRACT:

Background and purpose

previous RCT compared short-term results of above-elbow cast (AEC) with early conversion to below-elbow cast (BEC) in children with non-reduced diaphyseal both-bone forearm fractures. After 7 months both groups had comparable function. Our primary aim was to investigate whether forearm rotation improves or worsens over time. Secondary aims were loss of flexion and extension of the elbow and wrist, patient-reported outcomes measures, grip strength ratio, and radiographic assessment.

Patients and methods

We performed long-term follow-up (FU) of a previous RCT. All patients were invited again for the long-term FU measurements. Primary outcome was limitation of forearm rotation. Secondary outcomes were loss of flexion and extension of the elbow and wrist compared with the contralateral forearm, the ABILHAND-Kids questionnaire and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, grip strength ratio, and radiographic assessment.

Results

The mean FU was 7.5 (4.4-9.6) years. Of the initial 47 children, 38 (81%) participated. Rotation improved in both groups over time, with no significant difference in the final forearm rotation: 8° (SD 22) for the AEC group and 8° (SD 15) for the BEC group with a mean difference of 0° (95% confidence interval -13 to 12). Secondary outcomes showed no statistically significant differences. Finally, children < 9 years almost all have full recovery of function.

Conclusion

Long-term follow-up showed that loss of forearm rotation after a non-reduced diaphyseal both-bone forearm fracture improved significantly compared with that at 7 months, independent of the initial treatment and children aged < 9 will have almost full recovery of function. This substantiates that the remaining growth behaves like a "friend" at long-term follow-up.

Project description:BACKGROUND:Distal radial fractures are common traumatic injuries, but their management remains controversial also in case of conservative treatment regarding the type of immobilisation. Hence, we conducted a two-arm, parallel-group, prospective randomised trial to compare the capacity of long casts (above-elbow) and short casts (below-elbow) to maintain the reduction of extra-articular distal radius fractures with dorsal displacement (AO/OTA classification: 2R3A2.2). METHODS:Seventy-four eligible patients with AO/OTA 2R3A2.2 fractures treated with closed reduction and cast immobilisation were randomised to the long cast group (n°= 37) or to the short cast group (n°= 37). Baseline radiological parameters, radial inclination (RI), radial height (RH), ulnar variance (UV) and palmar tilt (PT) were taken, and compared with clinical (DASH, Mayo Wrist and Mayo Elbow) and radiological scores taken at 7-10 days, 4 weeks and 12 weeks. Furthermore, to evaluate correlations between radiological parameters and functional outcomes, patients were divided into two groups according to whether or not their radiological parameters at Follow-ups 2 and 3 were acceptable, i.e. within the range 11-12 mm for RH, 16°-28° for RI, - 4-+ 2 mm for UV and 0°-22° for PT. RESULTS:Patient demographic and baseline radiological parameters were similar between groups. At follow-up, there were no statistically significant differences between the two types of cast in terms of RI, RH, UV or PT, or Mayo wrist or DASH scores. Short cast group patients displayed better Mayo elbow score at follow-up 2 (4 weeks), but this difference was no longer statistically significant at follow-up 3 (12 weeks). No statistically significant differences in clinical outcomes were found between patients who presented acceptable radiographic parameters at follow-up and those who did not. CONCLUSION:As there were no significant differences between short casts and long casts in terms of fracture reduction maintenance or clinical outcomes, short casts are an effective method of post-reduction immobilisation in AO/OTA 2R3A2.2 fracture of the radius. Radiological parameters outside the range conventionally considered acceptable do not preclude a satisfactory clinical outcome. TRIAL REGISTRATION:ClinicalTrials.gov PRS, NCT04062110.

Project description:BackgroundDynamic compression plate (DCP) osteosynthesis is the gold standard for treating forearm diaphyseal fractures, providing stability and promoting healing. Locking plates (LPs) are increasingly used in modern fracture management but may increase the risk of nonunion if applied with excessive rigidity and without proper fracture site compression. The purpose of this study is to compare the nonunion rate between LPs and DCPs.Materials and methodsWe conducted a retrospective study by reviewing the medical records and radiographs of 515 patients diagnosed with radial and/or ulnar shaft fractures at three trauma centers between 2014 and 2019. Inclusion criteria were patients treated with locking plates (LPs), locking compression plates (LCPs), or dynamic compression plates (DCPs) who had at least 9 months of outpatient follow-up and imaging assessments. Exclusion criteria included treatment with other methods, hospitalization for pathological fractures or implant removal, or incomplete surgical records. Data on patient demographics, injury details, and surgical outcomes were collected to compare nonunion rates, as well as early and late complications, between the LP and DCP groups.ResultsA total of 368 patients were included in the analysis. Among them, 132 (35.9%) had isolated radial shaft fractures, 116 (31.5%) had isolated ulnar shaft fractures, and 120 (32.6%) had both-bone fractures. Of these, 124 patients received LP implants, 98 were treated with LCPs, and 146 were treated with DCPs. Early complications were comparable among the groups; however, the nonunion rate was significantly higher in the LP group (18.5% versus 11.2% versus 6.2%, p < 0.007). Logistic regression identified LP use [odds ratio (OR): 3.05, 95% confidence interval (CI) 1.24-7.53] as a significant predictor of nonunion. Notably, LPs lacking dynamic compression functionality were associated with markedly higher odds of nonunion in radial shaft fractures (OR: 26.94, 95% CI 3.52-206.15). These findings collectively indicate that LPs increase the nonunion rate in forearm fractures.ConclusionsUsing LPs without compression functionality to treat forearm diaphyseal fractures increases the nonunion rate, particularly in radial shaft fractures. Therefore, we recommend using LCPs or DCPs for forearm diaphyseal fractures to ensure adequate compression at the fracture site during fixation, thereby promoting optimal bone healing rates.Level of evidenceLevel III: retrospective comparative therapeutic study.

Project description:BackgroundDiaphyseal radius and ulna fractures require surgical fixation in adults. Open reduction and internal fixation (ORIF) have been considered the gold standard of treatment. The recent development of an interlocking intramedullary nail (IMN) has provided an alternative treatment method for these fractures. The objective of this meta-analysis is to compare the outcomes and complications of IMN versus ORIF for diaphyseal forearm fractures in adults.MethodsMEDLINE and Embase were searched from January 1, 2000, through January 7, 2024. All English-language studies were included comparing radiographic and functional outcomes for interlocking IMN fixation and ORIF of diaphyseal forearm fractures in adults (age ≥ 18 years). Study demographics, fracture data, functional outcomes, radiographic outcomes, and complications were extracted. Study quality was determined using the ROBINS-I criteria for cohort studies and the Cochrane risk of bias 2.0 (RoB 2) tool for randomized controlled trials. Meta-analysis of included studies used odds ratios and standardized mean difference when appropriate. Data was analyzed using subgroups of all diaphyseal fractures (including isolated radius or ulna fractures) and those with BBFFs.ResultsNine studies were included for analysis. There were 42 isolated radius, 80 isolated ulna, and 116 both-bone fractures (BBFF) treated with IMN and 36 radius, 81 ulna, and 116 both-bone fractures treated with ORIF. Compared to ORIF, IMN of diaphyseal forearm fractures appeared to be associated with shorter operative times and a lower overall complication rate. Time-to-union and the rate of nonunion following IMN were similar to ORIF. According to the Grace-Eversmann score, functional outcomes tended to be better following IMN, but DASH scores were similar between fixation strategies.ConclusionsOur findings suggest that interlocking IMN can be a safe and effective treatment option for simple and complex diaphyseal forearm fractures in adults. Further high-quality studies are needed to define indications for treating diaphyseal fractures with an interlocking IMN.Level of evidenceTherapeutic Level IV.
